I've gotten so many bad gifts! My parents were always very good to me, but the rest of the family never seemed to get it through their heads that just because I was a girl didn't mean I liked girly things. I got frilly dresses and ugly sweaters that my mother made me wear once each, when the appropriate relative was visiting; I got a Barbie doll that I played with exactly once; I got one of those baby dolls where you give it water and then it pees... All I wanted was some Legos and maybe a nice outfit or two.
I think the worst gift I've ever gotten was a wedding gift from my husband's cheap cousins. They are actually quite well-to-do, but they always give cheap gifts. It was a
stainless steel 2-tier serving dish. I am 99% certain that it was a re-gift and that the original gift-giver couldn't have dropped more than $50 on it. Maybe for a housewarming or engagement gift, but for a wedding?!
The same cousins gave my husband a
dictionary for his bar mitzvah! Worse, it was part of a lot that had been misprinted and was missing several letters of the alphabet. Yeah, they got that off the clearance rack.

We've been invited to their son's bar mitzvah; I suggested he give the dictionary back.
